A Correct answer
Explanation

Let ages be 5x and 4x. Three years later: (5x+3)/(4x+3) = 11/9. Cross-multiplying: 45x + 27 = 44x + 33, so x = 6. Anand's age is 4x = 4 * 6 = 24.

AI explanation

Let Sunita's and Anand's present ages be 5x and 4x. Three years hence, their ages will be 5x + 3 and 4x + 3, so we can write the equation (5x + 3) / (4x + 3) = 11 / 9. Cross-multiplying yields 45x + 27 = 44x + 33, which simplifies to x = 6. Substituting x into 4x gives Anand's present age as 24.
